yi'ippiaeima' m e e- To nib/omit Mag concern f Be, itfknown that I, Enwm' F. WHITE, a

resident er Hollidaysburg, inth'e countyiof Blair and State of' -Pennsylvania, have mvented a. new and useful I'rnprovemeiit -in Hot-Water Heaters; and 'Ldo hereby declare thefollowing to be a full, clear,fand exactdescription thereof. I j l My invention relates to certain improvements in hot-water heatersjsuch. as used 'for i any regular hot-water heating system,"

its ob ect I being to j provide heating-boiler adapted fofirapid heating {of the water;-

proper circulation of the same, to overcome the gathering of air in any portion-of the boiler itself and the consequent knocking or noise arising from the" same, and provide a sectional boiler'whichcanbe easily'erected and can .be used, if desired,without thence cessity of inclosing in'brickwork, while the body thereof can be insulatedso as to prevent the radiation of heat.

To, these ends my inventioncomprises, generally stated, a hot-water, heater formed in holloti sections eachfpro'vided with outer vertical legs extending up to a continuously upwardly curved cross portiJn or waist, a

central vertical riser and two side risers extending up fromthe waist portion and connected to an upwardly-curved top portion,

the side risers being setin from the vertical legs, and a fire-grate of the full width between I said legs, as Well as in other improvements to" be hereinafter described. v

To enable others skilled'in the 'art to employ my invention, I will describe the same more fully, referring to the accompanying drawing, inwhich Figure 1 isa front view of a boiler embodying the invention. Fig. 2 is a side view of one of the sections' set in place within the heater. Fig. 3 is a longitudinal section on the line 3 3, Fig. 2. Fig. {is a vertical crosssection onxthe line 4 4, Eig. 3, and Figs. 5 and 6 are detail views. v a

The boiler-sections forming the improved heater are made of separate castings adapted to be nested together and'the may be in closed in any suitable way. hey are specially adaptedghowever}, for being nested together in'such way as toform a complete boiler without brick inclosure, the main portion of the boilerbeing 'covered with asbestos or like filling ,viding means for supporting the same.

waist portion 9 starts below the side risers 10,

or arch ext'endingfrom the legs 8*to the cenward passage to that central riser. The verortion 9 some distance in from its point of section narrower than the lower portion 9 shall be upon gradual upward curves which central space 13 below the waist portion forms thefire-chamber, while the spaces 15 between the central riser 12 and the side risers 10 form the return flues'to the smoke-' the walls of the hot-water heater and .the

Above this front base-cast ing 3 is the cross-leg 5, hereinafter-referred to, and supported thereon is theiront box 6, containing ,the fire-door and forming. the

nace is the back'box 7, which also will be hereinafter described. The hollow sections forining'the heater-proper are each 'rovided extend full width, o'bEhe fire-chamber, 'so that the i I05 .18 absorbed is directly over the fire-chamber,

this including the waist portion 9 and the vertical risers therefrom inclosing the returnflues, the main body of the water to be heated being brought directly over the fire, which causes the very rapid absorption of the heat therefrom, while giving an extremely simple construction and one in which the water-can always pass in upward course from the bases of'the legs to the upper part of the heater through the several sections thereof without possibility of it being pocketed or held in its course. As shown in the drawings, to inclose the s aces between the sections, which are space sufliciently apart to permit the contact of the flame and heated gases with nearly the entire surfacelof eachheater-section, continuous webs or flan s 17 are formed near the outer edges of t 'e sections, running vertically along the leg portions, then on an n ward curve along the junction between the cg portions and waist portions of the side risers, and then around near the upper edge of the top portion 11. There is a so a cross web or flange 18 extending across from the flanges 17, near the .to line of the waist portion 9 and connecting t e two, so 'as to close communication between the fire chamber 13 and the return-flues 15. These flanges are formed on each side of each section, and the flanges of two sections contact with each other as the sections are built up; and so form the continuous water-heater. It will be noticed that the flanges 17 are set in slightly from the outer edge of the heater, leaving the spaces :19 to befilled with asbestos or other cement 20, by which the sections are insulated.

Toform a water connection at the base of the vertical legs 8 and between the legs of the front section and so give circulation across j the lower portion of the boiler, the cross-leg 5, above referred to, is employed, this being a hollow casting fitting up with the base of the legs and having suitable water connections therewith, so that circulation can be main- ;tained from any suitable inlet-pipe, as the pipe 21.

The different sections are arranged to communicate with each other at the bases of their vertical legs 8 and centrally of the top portion 11, suitable circulation-passages 22 23 being formed and these portions of the I rabbetcd joints.

sections being fitted to each other by suitable The sections as thus constructed are held together by means of suitable bolts 24, extending through the passages 22 23 and bearing upon suitable caps 25, closing these passages in the end sections. The several sections composing the water-heater are thus secured by three bolts,

one at the base of each leg and one at the top of the boiler central thereof. It is found that in thus bolting, together the several sections an easier connection between them is obtained thanwhere the bolting is bases of the legs of the front sections;

of rectangular form, overcoming defects in 5 is bolted to and closes 'these passages at the The front box 6, resting, as above stated, upon the cross-leg 5, can be secured in suitable way to the flange 17 ofthe front heater section, such as by straps-26. It has the cross-web 27 uniting with the cross-flange 18 on'the front .section, so as to form a contin'uous return-flue over the fire-chamber.

The smoke-passage 16 is formed at the upper end of this front box 6. The back wall of the heater is shown as formed of the box 17 which hasthe side and top flanges 28, corresponding in position to the flanges 17, so as to close the rear portion of the boiler, and this back wall is secured to the boilersections by means of straps 29, connecting the flanges 17 and 28.

Toform the grate-bar supports, suitable lugs 30 are cast upon one of the front crosscastings and upon the back box 7, according to the desired height-of the grate within the fire-chamber. In Figs. 2 and 4 this grate is shown as placed below the vertical. legs 8.

In Fig. 3 it is shown as placed in line with the base portion of'said legs.

To properly insulate the heater, the basecasting, such as the castings 2, may be formed recessed on their outer faces, such' recessed portions being filled with brick, as shown at 31f The construction also providesa desirable vmeans for insulating, the' boiler-sections and yet permitting free circulation of heat practically around the entire hollow portions thereof exposed within the fire-chamber or return-fines. As above stated, the web-flanges 17 are set in only-a short distance from the outer edge of the sections. By-this construction the recesses 19 are formed extending from the bases of the sections upwardly over the same, which form proper seats for holding the asbestos or like insulating cement or filling, which can be simply filled within the same or extended overthe whole heater-surface, being held to place by means of such recesses 19, which insure the. proper, support of the cement filling.

In the use of the heater the-fire generated in the fire-chamber 13 can circulate upwardly around the hollow sections, passing upwardly around the vertical leg portions 8 and being directed in upward course around the waist portions 9 and following incourse back along the different sections to the throat portion 32, connecting the fire-chamber with the return-flues, and passing thence forward around the upper portions of the hollow sections to the escape-flue 16. In thus circulating through the heater the flame and heated gases have opportunity tocontact 5 ,j low fire -box can be employed in which the hollow sections and with all of the cenchamber to cause the flame and heated gases section is made zpracticall'y perfect.

to travel along through the same to the 'throat 32 is provided, and at the same time the circulation of the Water in each hollow The main" body of the water to be heated is brought directly over the fire, and a broad flame and heated products can contact with the greater portion of the walls of the different sections, so insuring the rapid absorption 'of the heat from the gases by the water and obtaining extremely high heating results. The heated water rises in its circulation within the vertical legs, and in its passage either upwardly in the waist portion or in the side and centralrisers 10.-and 12 into the top portion 1 1 the water passes in either 7 vertical or regular upward incline without encountering any abruptly-curved portion in which air might gather and lead to knocking or noise within the boiler, and ,a free and rapid circulation is induced through the pro vision of the upwardly-curvedwaist portion and theset-in side risers leading, Has .illustrated, into the curved top portion. "At

the same time proper cross circulation is obtained through the cross-leg 5, and the water may be'drawn off for circulation through any suitable pipe, such as the. pipe34, and returned through the pipe 21 to any portion at the base of the boiler. In this construction the spaces between. the different sections are in -losed' by metal and those portions properly protected by the asbestos filling within the recesses'19 and liability of great radiation fromthe heateris overcome.

- Practical use of the heater has proven it to give free circulation for the gases and rapid I curved'cross portion or waist, a central vertical riser and two side risers extending up from the waist portion and connected b an upwardly-curved topjportion, theside users being set-in from the vertical legs. c
